No more mud!
Okay so the rain season is almost upon us. I now have...what is left of it some grass left in his running area, mostly dirt. To avoid tracking mud into the house, I am contemplating throwing down three inches of sand and then medium size smooth river rock. I'm thinking this will make it easy to clean waste, wash the urine into the ground while keeping the odor level down, and keep him from tracking mud inside and onto my brand new carpets. The smooth rock will be easy on his pads.
Does anyone have a better idea?
